What Are Water Hammer Arrestor Valves In Plumbing

Plumbing Drains with a pipe

Water hammer is a common problem in plumbing systems that occurs when the flow of water is suddenly interrupted, causing pressure waves to travel through pipes. These pressure waves can result in loud banging sounds and even damage to pipes and fittings if left untreated.

Water hammer arrestor valves are a solution to this problem, designed to absorb the shock of these pressure waves and prevent them from damaging plumbing fixtures. Water hammer arrestor valves work by providing a cushion of air or gas that absorbs the shock of pressure waves caused by sudden changes in water flow.

They are typically installed near plumbing fixtures such as sinks, toilets, and washing machines, where water flow is likely to be interrupted frequently. By installing water hammer arrestor valves in these locations, homeowners can prevent damage to their plumbing system while also reducing noise levels associated with water hammer.

In this article, we will explore the benefits of installing water hammer arrestor valves, how they work, and provide tips for installation and maintenance.

Understanding Water Hammer in Plumbing Systems

Water hammer in plumbing systems refers to the sudden and forceful pressure waves that occur due to the abrupt stoppage or change of water flow. This phenomenon can cause damage to pipes, appliances, and fixtures.

There are several causes of water hammer, including high water pressure, improperly installed valves, and sudden valve closures. Preventing water hammer is important to avoid damage to the plumbing system and ensure its longevity.

One effective solution is the use of water hammer arrestor valves. These valves work by absorbing the shock caused by water hammer and reducing its impact on the system.

In the subsequent section, we will explore what these valves are in more detail.

What are Water Hammer Arrestor Valves?

Water hammer arrestor valves are devices used to prevent the occurrence of water hammer in plumbing systems.

There are several types of water hammer arrestor valves available in the market, including piston-type, diaphragm-type, and shock absorber-type valves.

These valves operate by absorbing or reducing the pressure surge that results from sudden changes in water flow.

Types of Water Hammer Arrestor Valves

There are various types of valves available for preventing water hammer within plumbing systems. Popular brands of water hammer arrestor valves include Sioux Chief, SharkBite, and Oatey. The cost comparison of different types can vary depending on the size and style.

One type of valve is the air chamber, which is a vertical pipe installed near the faucet or valve that creates an air cushion to absorb the shock waves caused by sudden changes in water flow.

Another type is the piston-type valve, which uses a spring-loaded piston to absorb the shockwaves and prevent them from traveling through the pipes.

A third type is the diaphragm-type valve, which uses a flexible diaphragm to absorb shockwaves and release them slowly back into the system.

Each type has its advantages and disadvantages, but all serve as effective solutions to prevent water hammer in plumbing systems. Understanding how these valves work is important in determining which one would be best suited for your specific needs.

Understanding the types of water hammer arrestor valves available in plumbing systems can help you make an informed decision when selecting one for your home or business. By comparing popular brands and considering factors such as cost and functionality, you can choose a valve that will effectively prevent water hammer while fitting within your budget.

Next, we will explore how these valves work in detail to provide insight into their inner workings and effectiveness at preventing water hammer.

How Water Hammer Arrestor Valves Work

Understanding the inner workings of water hammer arrestor valves can provide valuable insight into how they effectively prevent sudden changes in water flow from damaging plumbing systems. Water hammer arrestor valves are designed to absorb and dissipate the energy caused by a sudden change in water pressure or flow, which prevents the pipes from vibrating, shaking or making loud noises. These design features enable the valve to act as a shock absorber that reduces the intensity of hydraulic shockwaves in the plumbing system, thereby protecting it from damage due to water hammers.

The effectiveness of water hammer arrestor valves is dependent on their design, size, and placement within the plumbing system. Proper installation ensures that these devices perform optimally and reduce noise levels significantly while protecting against potential property damage or safety hazards. Understanding how these devices work can help homeowners appreciate their value and make informed decisions when considering investing in them for their properties.

Installing these valves provides several benefits such as reducing noise pollution and extending the lifespan of plumbing fixtures without compromising safety or performance levels.

Benefits of Installing Water Hammer Arrestor Valves

The installation of water hammer arrestor valves provides several advantages, including a reduction in noise levels, prevention of damage to plumbing fixtures and appliances, and an increase in the lifespan of pipes. These benefits make water hammer arrestor valves cost-effective solutions for homeowners who want to preserve their plumbing systems. Noise from water hammer can be disruptive, but with the installation of these valves, it is significantly reduced. Additionally, water hammer can cause damage to appliances such as washing machines and dishwashers by loosening connections or damaging internal components. The use of these valves eliminates this risk and extends the life of appliances. Finally, without these valves, frequent pressure surges caused by water hammer can put stress on pipes and fittings leading to leaks or ruptures over time. By reducing pressure surges within the system through the use of these valves, pipes are protected from potential damage which ultimately leads to extending their lifespan. To further understand the advantages provided by installing water hammer arrestor valves see Table 1 below:

| Advantages | Explanation |
